The conversion part is provided with a positive end and a negative end, the conducting strips 13 can be completely connected with the positive end and the negative end, and also can be partially connected with the positive end and the negative end, so that the plurality of sharp needles 12 can be completely and electrically connected with the positive end or the negative end, or one part is electrically connected with the positive end and the other part is electrically connected with the negative end, and therefore when air flows through the ion sterilization device, the air can be ionized to generate positive ions, negative ions or positive ions and negative ions, and the sterilization and health care requirements of users can be better met.

Obviously, two or three or more sharp pins 12 may be provided on each conductive plate 13. It should be noted that, in the present embodiment, the specific number of the tip pins 12 and the conductive sheets 13 is not limited, and the above description is only an exemplary description, and should not be construed as limiting the number of the tip pins 12 and the conductive sheets 13.
